Dementia is a term used to describe a group of conditions marked by a decline in cognitive abilities—such as memory, behaviour and communication—that interfere with daily life. Alzheimer’s disease is the most common form, but there are many types of dementia. It’s not a normal part of aging but it is very prevalent in our ageing population especially women.
In Australia, more than 411,000 people were living with dementia in 2023, and that number is expected to more than double by 2058. There is no known cure for Dementia, however there have been numerous prevention strategies recommended by neurologists that are now more important than ever. It is best to start these strategies as soon as possible. One recommended strategy to prevent and manage the progression of dementia is EXERCISE!!!
Encouragingly, research shows that regular physical activity can significantly reduce the risk of developing dementia. Exercise improves blood flow to the brain and boosts levels of brain-derived neurotrophic factor (BDNF), which supports neuron growth and survival. The brain is fuelled by oxygen, so increasing your body’s oxygen (by exercising) will allow for your blood to transport oxygen to the brain more freely. This allows for better mental acuity and protects brain cells.
Another huge benefit of exercise is the anti-inflammatory effect on the whole body. It is proven that less inflammation in the body (especially the brain) the more protected your body is against dementia and other chronic diseases.
Moveology’s Exercise Physiologists recommend a combination of three types of exercise which is backed by evidence.
Aerobic Exercise: Activities such as brisk walking, swimming, or cycling improve cardiovascular health and circulation, essential for brain function.
Resistance Training: Using weights or resistance bands helps build muscle and supports cognitive health by increasing hormones.
Balance and Flexibility: Practices like Pilates, Yoga and Tai Chi enhance coordination and reduce fall risks, which are particularly important for older adults.
For beginners, it’s best to start slow—just 10 minutes a day—and build up to at least 150 minutes of moderate activity per week, along with strength exercises twice a week.
Exercise not only benefits physical health, but it’s one of the most promising ways to maintain cognitive function and reduce dementia risk. In the face of rising dementia cases, keeping active could be one of the simplest and most powerful tools we have.
